Enhancing Remineralization

Recent research findings on fluoride treatment for the initial caries lesion include:
1. Three applications of fluoride varnish in one week provide greater caries protection than one application every six months over a one-year period. Fluoride varnish is best applied immediately after tooth cleaning and should be protected as long as possible, preferably at least 10 hours.
2. Fluoride varnish and topical fluoride gel appear to be equally effective.
3. Fluoride varnish can be applied more frequently than a gel.
4. Fluoride varnish should be applied to smooth surfaces and as sealants to fissure sites.
5. Fluoride varnish is useful in children (infant nursing caries).
